            <h1>GnssAntennaDefinition (file format)</h1><p>

Contains a list of GNSS antennas which are identified by its
name (type), serial, and radome. Each antenna consists of
antenna center offsets (ACO) and antenna center variations (ACV)
for different signal <a class="groops-class" href="gnssType.html">types</a> (code and phase).
The ACV values for each type are stored in an elevation and azimuth dependent grid.</p><p>
